Rear end Q's

[DBasher]

Need some help on what exactly I need to go from my 2.41 to a 4.10 ratio in the 10 bolt I have. Looking at Randy's R&P site it looks like I need a new carrier for anything bigger than a 3.08....what else is needed?

The axle is out of a 78 Camaro, I still need to check if its 28 or 30 spline and like I said its currently a 2.41 ratio.

Thanks for any input
Dan
